ClassNotFoundException when running an executable JAR - java

I'm using JRAW (A Java Reddit API) and JDA (Java Discord API) with Maven, in order to make a discord bot for a server.
When I run my code in my IDE (IntelliJ IDEA) it works as intended although if I try to compress and run the code in an artifact (more precisely, a .jar file), it throws a ClassNotFoundException (kotlin.Pair).

Spigot/Bungeecord Hibernate - Invalid logger interface org.hibernate.internal.CoreMessageLogger

I tried using Hibernate ORM to handle my BungeeCord database mappings. I've used it before and had no problems doing so.
Now I revisited Minecraft programming and could not get Hibernate running.
My pom.xml is:

A quick google search didn't really help. I found a comment saying I have to initialize the logger with Hibernate.initalize(object). I could not get that to work either.
Thanks in advance for any help! :)
I don't know how class loading works in this "environment", but the hibernate-core.jar should contain a class called org.hibernate.internal.CoreMessageLogger_$logger, which is the logger implementation that apparently can't be found. Maybe the class loader is broken?
Your maven shade plugin contains the following:
<configuration>
<minimizeJar>true</minimizeJar>
</configuration>
This causes all the logging dependencies to be dropped while shading. Removing this line will fix the issue.

Error when using the logs in Quarkus with logger jboss

Good afternoon, I have a query, I am starting in Quarkus and I have a problem with the use of logs in it, I am working with a simple service that uses the GET verb, when placing the line of logs it throws me an error of java.lang.NullPointerException. This is my main code:

What could be happening, I don't understand
You are not injecting the logger. You can change the code to:
#Inject
AgroalDataSource defaultDataSource;
#Inject
Logger log;
By the way, Quarkus offers an additional way to get the logger without injection:
package com.example;
import io.quarkus.logging.Log;
class MyService {
public void doSomething() {
Log.info("Simple!");
}
}
#Davide answer is totally right, I just wanted to add that you can use constructor injection:
private final AgroalDataSource ds;
private final Logger log;
public FindPrepaidSubscriberICCID(AgroalDataSource ds, Logger log) {
this.ds = ds;
this.log = log;
}
Constructor injection tends to ease testability (because you can create instances of your objects passing spies or mocks). It also makes sure you do not write to the managed fields (as the fields are final).

vertx run with metrics enabled in cluster

OS: Linux
Vert.x Version: 3.3.3
Machines: Two different with
different IP within same subnet
I want to enable metrics monitoring for an simple ping-pong application, where I can watch how many packets were sent between the two nodes.
The measured metrics should be pushed over the eventbus and consumed by a website, providing a dashboard. Copied from the vertx examples on Github
Starting apps with following commands
Sender:
vertx run de.avm.boundary.Sender -cluster -cp target/vertx-ping-pong-3.3.3-fat.jar -Dvertx.metrics.options.enabled=true
Receiver
vertx run de.avm.boundary.Receiver -cluster -cp target/vertx-ping-pong-3.3.3-fat.jar
doesn't provide any metrics.

How can I enable Metrics?
Solved the problem by changing starting appliaction, especially the Sender an Receiver Verticles, in another war.
The best solution for me was starting the application with
Sender:
java -jar target/vertx-ping-pong-3.3.3-Sender-fat.jar -cluster -Dvertx.metrics.options.enabled=true
Receiver
java -jar target/vertx-ping-pong-3.3.3-Receiver-fat.jar -cluster -Dvertx.metrics.options.enabled=true
The pitfall is, that you must tell maven, especially the shade plugin, which them main class is. I have achieved this by defining a placeholder within the properties part in the pom.xml and passing the name of the main Vericle during maven build execution.
mvn package -DmainClass=Sender
This also results to place a fat-jar withing the target folder where the name of the passed parameter is included in the file name.
Here the modified pom.xml

Problems testing services created with maven-scr-plugin when using pax-exam

I've set up a very simple "HelloWorld" service to demonstrate my problem. It uses the maven-scr-plugin to generate a service descriptor and has a pax-exam unit test. But when I try to run 'mvn clean test' it blocks for a while before giving me this error:
org.ops4j.pax.swissbox.tracker.ServiceLookupException: gave up waiting for service com.liveops.examples.osgi.helloworld.HelloWorldService
If I run 'mvn -DskipTests=true package' and then run 'mvn test' (without clean)
it works. The difference seems to be the addition of this line in my META-INF/M
ANIFEST.MF file:
Service-Component: OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml
Does anyone know if there is a way to make sure this line is added earlier in the build process so that 'mvn clean test' will pass? Or is there something else I might be doing wrong?
For reference, here is the pom.xml, the service, and the unit test.

HelloWorld Implementation class
package com.liveops.examples.osgi.helloworld.internal;

import org.apache.felix.scr.annotations.Service;
import org.apache.felix.scr.annotations.Component;
#Component
#Service(HelloWorldService.class)
public class HelloImpl implements HelloWorldService
{
public String helloWorld(String personalization)
{
return "Hello " + personalization + "!";
}
}
The unit test
package com.liveops.examples.osgi.helloworld.internal;
import com.liveops.examples.osgi.helloworld.HelloWorldService;
import junit.framework.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.ops4j.pax.exam.Option;
import org.ops4j.pax.exam.Configuration;
import org.ops4j.pax.exam.junit.PaxExam;
import org.ops4j.pax.exam.util.PathUtils;
import javax.inject.Inject;
import static org.ops4j.pax.exam.CoreOptions.*;
#RunWith(PaxExam.class)
public class HelloImplTest
{
#Inject
HelloWorldService hws;
#Configuration
public static Option[] configuration() throws Exception{
return options(
systemProperty("org.ops4j.pax.logging.DefaultServiceLog.level").value("WARN"),
mavenBundle("org.apache.felix", "org.apache.felix.scr", "1.6.2"),
bundle("reference:file:" + PathUtils.getBaseDir() + "/target/classes"),
junitBundles());
}
#Test
public void testInjection()
{
Assert.assertNotNull(hws);
}
#Test
public void testHelloWorld() throws Exception
{
Assert.assertNotNull(hws);
Assert.assertEquals("Hello UnitTest!", hws.helloWorld("UnitTest"));
}
}
Use the ProbeBuilder to enhance your tested bundle:
#ProbeBuilder
public TestProbeBuilder probeConfiguration(TestProbeBuilder probe) {
probe.setHeader("Service-Component", "OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml");
return probe;
}
This most likely is all that's missing.
EDIT:
just in case you're trying to use pax-exam in the same bundle you need to take certain actions in your configuration method:
streamBundle(bundle()
.add(SomceClass.class).add("OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml", new File("src/main/resources/OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml")
.toURL())
.set("Service-Component", "OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml")
.build()).start()
a complete sample can be found at here
I may have a fix for this, though it seems a bit in-elegant. I can explicitly add the Service-Component to the maven-bundle-plugin section of the pom file.
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.name}</Bundle-SymbolicName>
<Bundle-Version>${project.version}</Bundle-Version>
<Export-Package>!${namespace}.internal.*,${namespace}.*;version="${project.version}"</Export-Package>
<Private-Package>${namespace}.internal.*</Private-Package>
<!--Explicitly add the components no that they can be found in the test phase -->
<Service-Component>OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml</Service-Component>
</instructions>
</configuration>
<executions>
<execution>
<id>generate-manifest</id>
<phase>process-classes</phase>
<goals>
<goal>manifest</goal>
</goals>
</execution>
</executions>
</plugin>
Please let me know if anyone can think of a better way.
The Maven SCR Plugin only generates the service component descriptors but it does not include them in the manifest automatically.
So there's nothing inelegant about including a <Service-Component> instruction in the Maven Bundle Plugin configuration, that's just the documented usage.
Since the manifest header is missing, SCR does not register any services on behalf of your bundle, and that's why Pax Exam can't find the required service.

HtmlUnitDriver seems to be missing HTTP Components?

To get started with Selenium2 and the HtmlUnitDriver I created a test project. As long as I'm using the FirefoxDriver, everything is working perfectly. But as soon as I switch to HtmlUnitDriver I get the following exception. Am I missing some dependencies? I found no documentation telling me which Maven dependencies I have to include, to get this working.

A simple Test class:
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
public class GoogleTest {
private static final String SEARCH_BUTTON = "gbqfb";
public final static String SEARCH_BAR = "gbqfq";
public final static String RESULT_STATS = "resultStats";
#Test
public void testMe() {
// does not work:
// java.lang.NoClassDefFoundError:
// org/apache/http/impl/conn/PoolingClientConnectionManager
HtmlUnitDriver wd = new HtmlUnitDriver();
// FirefoxDriver wd = new FirefoxDriver();
wd.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
wd.get("http://www.google.de/");
WebElement searchBar = wd.findElement(By.id(SEARCH_BAR));
WebElement searchButton = wd.findElement(By.id(SEARCH_BUTTON));
searchBar.click();
searchBar.clear();
searchBar.sendKeys("Selenium Test");
searchButton.click();
WebElement resultsText = wd.findElement(By.id(RESULT_STATS));
String resultsFound = resultsText.getText();
wd.close();
Assert.assertTrue(resultsFound.startsWith("Ungefähr 34.100.000 Ergebnisse"));
}
}
EDIT: fixed missing dependency!
Try moving this block:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
<version>${selenium.version}</version>
</dependency>
from the <dependencyManagement> section into the <dependencies> section of the POM (which is where you have the FireFox driver included).
I got same error and here is how I solved - This error will come if your httpclient.jar, httpcore, httpmime jar files versions are not matching the parent 3rd party classes. I had httpclient-4.0.3.jar versions. Downloaded and added httpclient-4.2.jar to lib of my NetBeans. Similarly added httpcore-4.2.jar and httpmime-4.2.jar. The class executed!!
